Galaxy Note8: Why is the fingerprint reader on the back?

Last Update Date : Apr 09. 2018

Samsung have moved the fingerprint reader to the back to create the Galaxy Note8’s bezel-less Infinity
displayand to optimize the design of the device. It’s same as the S8 but rearranged back side design.
To prevent contamination of the camera lens due to fingerprint recognition, the Flash/HRM part was
inserted between the camera and the fingerprint sensor and it increased distance between camera
and fingerprint sensor.
